Boldin actually signed a five-year contract through the 2018 season, but the deal voids to the widely reported two-year, $12 million contract. Boldin agreed to the contract extension last Tuesday, but it was not signed until Friday, the source said.

Boldin received a $4.545 million signing bonus with a first-year guaranteed base salary of $955,000. He is scheduled to earn $5.5 million in base salary in 2015 with $3 million guaranteed. The deal includes $8.5 million in guarantees. During the 2014 and ’15 seasons, Boldin will earn $31,250 for every regular-season game he suits. Those per-game roster bonuses could total as much as $500,000 both seasons. Even if Boldin is not on the 49ers in 2016, he is still scheduled to count $2.727 million against team's salary cap that season.
